With good fucking reason, I’d say.
I think there are plenty of examples of both. Some of the early Gen13 stuff with Rainmaker was pretty goofy and sometimes gross, but then you have Batwoman. There’s both.
But absolutely, a lot of writers are FAR more comfortable adding lesbian characters or bi- female characters than they will ever be adding gay guys. And it’s probably for the exact reasons you suspect.
I am always happy when we take steps forward, but I want to be sure they actually ARE steps forward and not just a new kind of pandering.
